Specification forming part of Letters Patent`N0. 109,97*?. datedDecember 61 1870.

-To all 'whom it may concern:

Beit known that we, SAMUEL S. VoLLUM and WILLIAM H. GREEN, of the city,county, and State of New York, have invented a new and ImprovedLnbricator.; and we do hereby declare that the following is a full,clear, and

' exactdescriptionthereof, which will enable others skilled in the artto make and use the same, reference being had to the accompanyingdrawings, forming part of this specification.

This invention relates to a new and luseful improvement in a device forconveying-lubricating" material or substancesas tallow, grcase,orcthersemi-liquid orsolid substancesto the arms of carriage-axles, or tojournals, boxes, orbearings; and it consists in a lubricating-cup with atubular stem, and in a tight- 4iitting cap thereon, and in a'pstou orfollower D is the cap, which screws tightly on the cup A.

Eis the p1stonrod, which works through the cap with a screw-thread.

The lubricating,r material is placed in the" cup after remoi'linfs.` thecap and piston. The l cap is then screweddown tightly, and thesemifluidorsolid lubricating material is forceglA from the cup by screwing downythe pistou. The piston or follower is designed to work tightly in thecup, so lthatpthepower applied in screwing down the piston vserves toforce the materialfrom 'the cup and onto the frictional surface by apositive motion, thus rendering clogging or gumming of the o'riticeimpossible.

Having thus .described our invention, we claim as new and desire to,secure by Letters PatentrEhe combination of solid cap D, solid disk C,cup A, and pipe B, each constructed and relatively arranged as and forthe purpose specified.

The above speciiicationv of our invention signed by us this 28th day ofMarch, 1870.
